This blog post is about creating an Twitter Bot to tweet messages using Azure Automation. The steps and the script itself are based on Trevor Sullivan's TechNet Gallery post. His post assumes that you are familiar with some Azure Automation steps. So I am going to describe the required steps in more detail.

Ensure that you've added your mobile phone number to your Twitter account before creating a new Twitter application. This is a requirement for creating Twitter applications.

Log on to Twitter using the Twitter account you want your Twitter Bot to post as.You'll see something similar as this:

Just click Create New App.

Enter the information as needed. The application name must be a globally unique name. So it might be tricky to find a suitable application name. Click Create your Twitter application to finally create the application.

Select Keys and Access Tokens and copy the Consumer Key (API Key) and the Consumer Secret (API Secret) value into a text editor of your choice.

Further down on the same web page you'll find the Your Access Token section.

Click Create my access token.

After you've created the access token, copy the Access Token and the Access Token Secret to your text editor document. You'll need all four values in just a moment.

Step 2: Install PoshTwit locally

The Azure automation component will require application credentials for posting Tweets on your behalf. These required credentials are stored in a JSON file. Yo do not need top worry about the JSON data format.

The PoshTwit PowerShell module helps you to create the required JSON file.

The simpliest way to get the PoshTwit module is by installing the module directly from the PowerShell Gallery using an Administrative PowerShell session.

Install-Module PoshTwit

If you cannot use the Install-Module cmdlet, use the link provided in the Links section.

Remember that this step is only needed to create the JSON file containing the required credential information for Azure Automation.

After you've successfully installed the PoshTwit module, call the Set-PoshTwitToken cmdlet using all four Twitter app credential information to create the authentication JSON file.

You should see your Twitter application authentication information. You will nedd to copy & paste this string including the curly brackets as account credentials at a later step.

Step 3: Setup Azure Automation

Log on to the Azure Portal and create a new Azure Automation account. The Azure Automation will host your automation runbooks, variables and other settings. You can have multiple Azure Automation accounts. This is especially usefull when you want to delegate access and control of Automation accounts to different members of staff.

Click '+', enter Auto as search text and select Automation.

Click Create on the next blade.

Configure your new Azure Automation account by using a unique name, select the appropriate Azure subscription, create a new Resource Group or use an existing, select the Azure location, leave Yes as the default option for creating an Azure Run As account, select the checkbox to pin the Azure Automation account to your Azure dashboard, and click Create.

After you've been redirected to the Azure Dashboard wait for the Azure Automation Account to be created. If you are not redirected to the Azure Automation blade automatically, select the Automation Account tile on the Azure dashboard.

Select Process Automation - Runbooks. You'll notice two tutorials and two tutorial scripts which are automatically provisioned for you.

Click Add a runbook to create the Twitter Bot runbook.

The next step requires that you've download the Tweet-PowerShellTips.ps1 script. If you haven't, download it now.

Select Import an exisiting runbook and browse for the downloaded PowerShell script on the next blade. After selecting the PowerShell file the fiel will be uploaded and validated automatically. The Runbook type and Runbook name properties will be set automatically for you. Just enter a short description for your runbook. Click Create.

The uploaded PowerShell script utilizes the PoshTwit PowerShell module. This PowerShell module needs to be available within the Azure Automation account as well. Additonal PowerShell modules are configured within the Shared Resources section of your Azure Automation account. The PoshTwit module is added from the PowerShell Gallery.

Click Import to import the PowerShell module to thre shared ressources of your Azure Automation account. Click OK on the following blade. Close the PoshTwit module blade.

Now you'll add the required Twitter application credentials to the Shared Resources of the Azure Automation account.

Select Shared Resources - Credentials and click Add a credential.

Use TwitterCredential as Name and User name. The variable is accessed by the PowerShell script using the cmdlet

Get-AutomationPSCredential -Name TwitterCredential

Now copy and paste the full JSON file content as Password and Password confirmation. Click Create to save the new credential information.

Select the new runbook from the list of runbooks to edit the runbook properties.

Click Edit to edit the PowerShell code to adjust the tweets to match your needs (at least). YOu are able to edit the PowerShell code directly from the browser window.

Ensure to click Save, after you've edited the PowerShell code.

Each time you've edited an Azure Runbook, you need to publish the new version of the runbook. Click Publish and confirm the publishing with Yes.

You can test your runbook using the Test pane. The script itself will not write any output to the output windows, as the script does not use any Write-Output cmdlets.

You can add the following PowerShell code to the script to output the Tweet Id and Tweet text.

Write-Output "Publish Tweet $($TweetId) | $($TweetList[$TweetId])"

As a last step you need to create a schedule to post random tweets automatically. Automation schedules are created as shared resources again.

Select Shared Resources - Schedules and click Add a schedule.

Configure a schedule name, the start date, the schedule time zone, and the recurring interval. Click Create.

Select your runbook to link the just created schedule.

Select Schedules and click Add a schedule.

Click Link a schedule to your runbook, select the schedule and click OK.

The runbook schedules overview will show an information when the next run will be initiated.

That's it. Your Azure Automation Twitter Bot is up and running.

Now you can simply edit the runbook, add new tweets to the string array, save the changes and publish the changed runbook for production use. As long as the changes are not published, Azure Automation will use the last published version of the runbook.

Description

Using this script you can test the domain availability in Office 365 and Azure AD. As there are different closed Office 365 and Azure AD regions you need to test per dedicated closed Office 365 region.
